On the way to school one day, Tomoya Okazaki meets a strange girl talking to herself named Nagisa Furukawa. Later in the day, Tomoya has a conversation with Nagisa during lunch and learns that she is repeating her last year of high school, and wants to join the now-disbanded drama club. After school, Tomoya goes to Nagisa's family bakery and meets her parents; he is invited to have dinner with them.

Nagisa admits to wanting to restart the drama club, and Tomoya helps Nagisa to create advertisement posters which they place around school. At school that day, Tomoya meets two other girls: a strange genius named Kotomi Ichinose, and a first-year named Fuko Ibuki. Later that day, Nagisa finds out Tomoya used to play basketball, and invites him to play a game the next day. However, it is later revealed that his father injured Tomoya's arm in a fight; as a result, he is unable to play basketball anymore.

After the previous night's events, Tomoya goes to see if Nagisa is okay, and finds out that she has been physically weak all her life. While walking back from the bakery, Tomoya helps get a strange electrician out of a jam and he gives Tomoya his card, finding his name to be Yusuke Yoshino; Youhei later reveals that Yusuke is a retired professional musician. After school the next day, Tomoya helps Nagisa get more self-confidence for the drama club by acting as a new member of the club asking questions.

Tomoya runs into Fuko again at school, and she tries to invite him to her older sister's upcoming marriage ceremony, but Tomoya is not interested. Tomoya gets Youhei to help reform the drama club by bribing him with bread from Nagisa's family bakery. Nagisa tries to get the help of Ryou and Kyou in reforming the drama club, and Tomoya even tries to ask Tomoyo and Kotomi if they would like to join; Tomoyo is trying to become student council president, and Kotomi does not give an answer. Tomoya and Nagisa later go see Fuko about the club, and he discovers from Nagisa that Fuko is supposedly unconscious in a hospital.

In order to help Fuko out, Tomoya and Nagisa take her to stay at Nagisa's house for the time being. Nagisa's family helps with carving more starfish out of wood, and at school Tomoya and Nagisa help with passing them out to students. Later, Fuko talks about how she has wanted to attend classes, but has never been able to. Tomoya makes arrangements with Youhei, Kyou, and Ryou to act as classmates in Fuko's very first high school class, and even Sanae comes to act as the teacher.

Tomoya and Nagisa invite Fuko's older sister Kouko to the Founder's Festival. In the meantime, Fuko hands out more carved starfish to students at the festival, and her fan club helps spread the word about Kouko's wedding too. Nagisa and Tomoya meet Tomoyo, who is wearing a bear suit to find people who are causing trouble, and manages to knock Youhei out a window for bothering a girl. When Kouko finally comes, she cannot see or hear her sister.
